In the no-load experiment of asynchronous motors, a three-phase voltage regulator is used to supply power, causing the stator terminal voltage to gradually decrease from (1.1-1.3) Un, and the no-load current to gradually decrease until there is a significant change in the motor speed and a significant increase in no-load current. Why does a decreas...

There are various methods for motor deceleration, and the following are some common methods:1. Using a reducerA reducer is a device specifically designed to reduce the speed of a motor. By connecting the motor to the reducer, the output speed of the motor can be effectively reduced while increasing the output torque.2. Using a frequency converte...

The DC brushless motor eliminates the carbon brush and slip ring structure, reduces friction losses, and significantly improves the efficiency of the motor. At the same time, the motor itself has no excitation loss, further improving the comprehensive power saving rate, which can reach 20% to 60%. This efficiency makes DC brushless motors perform w...

Sometimes, the deceleration motor may not rotate during use. So, let's summarize how to determine the quality of the three-phase asynchronous motor coil and what instruments should be used for inspection:1. A megohmmeter can be used to measure the insulation resistance between motor phases and phase to ground, and should not be less than 0.5 megoh...

In three-phase asynchronous motors, rated current refers to the current value of the motor when operating at rated power and rated voltage. Rated current is an important parameter in motor design and selection, used to ensure that the motor will not overload or overcurrent under normal operating conditions.The relationship between the rated curre...

Mechanical failure is a type of failure that typically occurs in the internal casing of a three-phase induction motor. These faults are further subdivided into three types, such as:1. Rotor wire breakage faultThe squirrel cage induction motor consists of a rotor bar and a short end ring. If these guide bars are damaged or locally cracked, then thi...

Ordinary motorA regular motor is a common type of electric motor commonly used for various power needs. It has the characteristics of high speed and low torque, and is not directly used in smart cars. The structure of ordinary motors is relatively simple, with low production costs, and does not have the feedback function of servo motors and the sub...

1. Drive mismatchThe stepper motor needs to be matched with the corresponding driver for use. If the driver used does not match the motor, it may cause the motor to shake. For example, if the driver used cannot provide sufficient current, the motor cannot function properly and is prone to vibration.2. Excessive motor loadThe stepper motor has a ma...
